Patented June 24, 1930 UNITED STATES PATENT OFFICE WALTER E. ROSE, 01 DENVER, COLORADO, ASSIGNOR OF ONE-HALF TO 0. W. ROSE, '01 DENVER, COLORADO SUPPORT WINDOW CLEANERS Application filed Hatch 1,

This invention relates to supports for Window cleaners and its main object resides in the provision of a gear of simple construction which can be suspended from a window sill in such a manner as to provide a safe and secure support upon which a person can stand outside the window in a position to clean the upper and lower sashes thereof. A further object of the invention is to provide in association with a support of the above described character, a belt for the support of the body of the cleaner, another object is to render both the support and the belt adjustable by simple means so that the device can be fitted to windows of different sizes and forms and made applicable to persons of different heights.

Another object resides in providing a support for window cleaners wvlmich is held without the use of hooks, eyes or similar fastening devices on the window frames or other parts of the building and which permits of the window being closed while the operator is outside the same, and still other objects reside in details of construction as will fully appear in the course of the following description.

In the accompanying drawings in which like characters of reference designate corresponding parts throughout the views,

ure 6, showing another modification in the construction of the support, and

by riveting the ends of the doubled straps as at 7 and they are reenforced by metal foot plates 8.

Transverse straps 9 fastened on the straps above the stirrups are provided with buckles 10 to embrace the ankles of a person standing in the stirrups and thereby holdthe feet in place. Adjustably secured adjacent the opposite ends of the straps, are flat anchorhooks 12 which in the operation clasp the window sill 13 at the inside of the wall 14 as best shown in Figure 1. i

The straps are adjustably fastened to the hooks by weaving the end portions thereof through parallel slots in the fiat shanks 12? of the hook, between flanges .12 which re enforce the hooks at opposite sides thereof.

The hooks are preferably lined with leather or other soft material as at 15, to prevent marring of the sills to which they are applied. When the hooks are placed in their operative position relative to a win,- dow sill the straps extend across the sill and the wall of the building in which the win- (low is fastened, so that the stirrups hang outside the wall to support the window cleaner in an upright position as shown in Figure 1.

At the points at which the straps bend across the edge of the wall, they are provided with saddles 16 of rubber or other flexible material, which protect the straps against wear. 'lhe'saddles are held in place on the straps by loops 1? which permit of the adjustment of the saddles along the straps and relative to the hooks, in accordance with the width of the wall to which the support is applied.

Secured to the straps at points between the anchor hooks and the saddles, is a belt consisting of a strap 18 having its ends adjustably fastened to the straps of the support, and two shorter straps 19 and 20 which are attached to the other and which may be fastened together by means of a buckle 21.

The belt thus associated with the support is fastened around the body of a window cleaner standing in the stirrups to prevent him from falling backward.

The adjustable connection between the ends of the belt straps 18 and the straps 5 of the support are established by means of metal buckles 22 composed of' flanged plates provided with parallel slots through which the straps are woven as best shown in Figure 4 of the drawings.

In order to hold the saddles in place on the straps, they may be fastened to the buckles 22 by means of short straps 23 connected by buckles 24.

It will be observed that when the support is applied to the window sill as shown in the drawings and hereinbefore described, the only parts passing underneath the window sashes are the fiat straps 5 so that the sashes may be lowered to the sill when the cleaner is outside the window and are thus easily reached.

The gear anchored on the sill will support the operator with the utmost safety and the adjustability of the parts of which it is composed permits of its use on sills and walls of different thicknesses and at the most convenient distances beneath the opening of the window. 1

Havin thus describedthe support in its preferred form, it is to be understood that variations and chan es in the construction and arrangement of t e constituent members thereof may be resorted to without departing from the spirit of the invention. For example, in places where a window sill of sufiicient size or strength is not available, the straps 5 may be secured by means of a strong rod 25 placed across the window frame on the inside of the building as illustrated in Figures 5, 6 and 7. The hooks on the straps may then clasp the rod as shown in Figures 5 and 6 or the straps may be fastened to the rod by loops 26 as illustrated in Figure 7.

The foot support which in the preferred form of the invention, is represented by the stirrups 6, is also subject to variations. In the construction shown in Figure 7, a platform 27 is suspended from the ends of the straps by means of bails 28, and this platform may be "provided withstraps 29 to secure the legs of the cleaner, if so de ired.

The platform may also be provided with sides to form a basket or box 30 in which the operator can stand, or a short ladder 31 may be suspended from the straps 5 so that the cleaner can change his position above the window sill to reach different parts of the window sashes.

The last-mentioned modifications have been shown in simple form inFigures 8 and 9.

The means for fastening the straps and for adjusting the length and relative positions thereof may also be changed within the scope of the invention.

It is to be understood that while straps of the kind shown in the drawings are preferable, any other flexible means such as thin metal strips, chains or ropes may be employed within the scope of the invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. An appliance of the character described comprising a support for the feet, straps to suspend the support outside a window, means to anchor the straps inside the window, and flexible saddles connected on the straps, to engage the edge of the wall outside the window.

2. An appliance of the-character described comprising a support for the feet, straps to suspend the support outside a window, means for anchoring the straps inside the window, a strap adapted to embrace the body of a person standing on the support, and buckles having pluralities of slots, the suspension straps and the ends of the bod strap being woven through the slots of eac buckle.

3. An appliance of the character described comprising a support for the feet, stra s connected. with the support to suspend t e same outside a window, and anchor hooks to clasp the sill inside the window, having pluralities of slots through which the straps are woven.

4. An appliance of the character described comprising a foot support, a strap for suspending the support outside a window, means for anchoring the strap inside the window, and a body belt includin a strap fastened to the suspension strap and adapted 'to embrace the body of a person standing on the support.

5. An appliance of the character described comprising an element having opposed members forming a loop, anchoring means at the free ends of the members, stirrups suspended from the members, and a body embracing means in the loop. between the members.

6. An appliance of the character described comprising two suspension members, a body strap having opposite portions connected withthe suspension members, and stirrups separately connected with the suspension members.

7 An appliance of the character described comprising two anchoring means, a foot support connected with each anchoring means, and a body belt connected with each anchoring means and with each foot support.

5 n testimony whereof I have aflixed my signature.
